Wow...I am very pleasantly surprised with the size and versatility of this product. I wanted to make sure I showed all aspects of this organizer tote in my pictures.
I am showing the pictures from the back of my Kia Sorento. It is pretty spacious, and yet the tote can take up some good amount of room. Or, if you choose, is big enough to hold quite a bit of stuff. The organizer comes in its flattened state. It is held closed by two buckles, one on each side. When you choose to open both ends, it has two big compartments. The compartments are held in place by the hard bottoms that you place in once opened. One of these compartments (left side in my pictures) has an insertable divider, held in place by Velcro. The other side is full. You can choose to have both sides completely full, if you wish, by taking the divider out. Also, as shown in the second picture, you can close one compartment by packing it in towards the middle. This is securely closed by another buckle in the middle. The big main divider in the middle is not removable, as it helps to support the stability of the bag. Although I have not tried a completely full and heavy load yet, the handles seem more than able enough to carry a good load of just about anything in this organizer. The combination of the reinforced bottom and the walls plus the dividers, make this a more-than-capable organizer to help in your car, or any room for that matter. I'm going to using this exclusively in my car as it has enough room for my cleaning supplies and some odds and ends toys for my young kids. It is stable enough to not be sliding around in my back and yet can pack up almost flat when not being used. I would estimate it closes down to about an inch and a half thick because of the walls and buckles, two at the most. But pretty impressive by my standards. Highly recommended!
As a side not, I am using this exclusively in the back of my vehicle. In my second row seats I carry two toddler car seats. Just putting this organizer in with only one side compartment open was a very tight fit. I know if I didn't have two car seats, this would be a much easier fit up there.
